First-aid measures

Description of first aid measures
General information:
Take persons to a safe place. Observe self-protection for first aid. Always seek medical advice in the event of contact with this
substance.
After inhalation:
Keep the patient calm. If unconscious place in stable sideways position. Protect against loss of body heat. If breathing stops,
administer artificial respiration. Seek medical advice immediately and clearly identify substance.
After contact with the skin:
Remove contaminated clothes at once. Wash off with plenty of water or water and soap immediately for 10-15 minutes. In serious
cases, use emergency shower immediately. Seek medical advice immediately and clearly identify substance.
After contact with the eyes:
Rinse immediately with plenty of water for 10-15 minutes. Keep eyelids well open to rinse the whole eye surface and eyelids with
water. Seek medical advice immediately and clearly identify substance. Continue to bathe eyes during transport to medical
practitioner.
After swallowing:
If conscious, give several small portions of water to drink. Do not induce vomiting. Seek medical advice immediately and clearly
identify substance.

Most important symptoms and effects, both acute and delayed
Any relevant information can be found in other parts of this section.

Indication of any immediate medical attention and special treatment needed
After inhalation: treat as early as possible using cortisone spray. Medical checks necessary up to a latency period of at least 24
hours. In the event of 1st degree burns use corticoid-externa. In the case of 2nd degree burns, use symptomatic treatment. Risk
of intra-abdominal gas developing if swallowed. Risk of perforation of the stomach.

Fire-fighting measures

Extinguishing media
Suitable extinguishing media:
alcohol-resistant foam , carbon dioxide , dry sand . Application of foam will release at least initially significant amounts of
flammable and corrosive vapors. These vapors could be trapped under the foam blanket.
Extinguishing media which must not be used for safety reasons:
water , extinguishing powder , halones .

Special hazards arising from the substance or mixture
Hazardous combustion products: hydrogen chloride .

Advice for firefighters
Special protective equipment for fire fighting:
Use respiratory protection independent of recirculated air. Use tightly fitting chemical protection suit (see section Exposure controls/personal protection).

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Wear personal protection equipment (see section 8). Task force: Use tightly fitting chemical protection suit (see section 8). Keep
unprotected persons away. Avoid contact with eyes and skin. Avoid inhaling mists and vapours. Do not walk through spilled
material. Ensure adequate ventilation. If material is released indicate risk of slipping.

Environmental precautions
Prevent material from entering surface waters, drains or sewers and soil. Contain any fluid that runs out using suitable material
(e.g. earth). Condense gasses/vapours/mists using a directed spray of water. Retain contaminated water/extinguishing water.
Dispose of in prescribed marked containers. For large amounts: Close leak if possible without risk.

Methods and material for containment and cleaning up
Do not flush away with water. For small amounts: Absorb with liquid, mainly acid binding material and dispose of according to
local/state/federal regulation. Cover larger quantities by near waterless foam and take up in container. Exhaust vapours. Clean up
with plenty of water.
Further information:
Eliminate all sources of ignition.

Reference to other sections
Relevant information in other sections have to be considered. This applies in particular for information given on personal
protective equipment (section Exposure controls/personal protection) and on disposal (section Disposal considerations).

Handling and storage

Precautions for safe handling:
Ensure adequate ventilation. Must be syphoned off in situ. Keep away from incompatible substances in accordance with section
Stability and reactivity. Spilled substance increases risk of slipping.
Precautions against fire and explosion:
Flammable vapors may accumulate and form explosive mixtures with air in containers, process vessels, including partial, empty
and uncleaned containers and vessels, or other enclosed spaces. Vapours heavier than air, therefore inflammable gas mixture
may form mainly near floor. Keep away from sources of ignition and do not smoke. Take precautionary measures against
electrostatic charging. Cool endangered containers with water.

Exposure controls / personal protection

Control parameters
Maximum airborne concentrations at the workplace:
CAS No. Material Type mg/m3 ppm Dust fract. Fibre/m3
7647-01-0 Hydrogen chloride AGW 3,0 2,0
7647-01-0 Hydrogen chloride EU 8,0 5,0
-
Hydrogen chloride (CAS-Nr. 7647-01-0): Refer to Technical Rules for Hazardous Substances "TRGS 900" for more details on the
German AGW.
hydrogen chloride (CAS no. 7647-01-1): the short-time exposure value of the EU threshold is 15 mg/m3 (= 10 ppm).

Exposure controls
Exposure in the work place limited and controlled
General protection and hygiene measures:
Do not breathe vapours. Avoid contact with eyes and skin. Do not eat, drink or smoke when handling. Wash hands at the end of
work and before eating.
Personal protection equipment: Respiratory protection gas mask filter ABEK P2 . In case of long or strong exposure: positive pressure self contained breathing apparatus .
Hand protection: Gloves are required at all times when handling the material. The selection of appropriate gloves not only depends on the material,
but also on other quality characteristics, and may vary depending on the manufacturer. Please observe information from your
glove supplier in terms of permeability and breakthrough time. Recommendation: Protective gloves made of 5-layer laminate of
PE and EVOH (4H) , Protective gloves made of butyl rubber , protective gloves made of fluorinated rubber . Breakthrough time >
6 hours . nitrile rubber protective gloves - Wear gloves for short periods only.
Eye protection: tight fitting protective goggles required . Where there is risk of splashing: protective shield . Provide work station with eye bathing
equipment. Do not wear contact lenses.
Skin protection: apron , protective clothing, face protection, neck protection , acid-proof protective clothing .

Exposure to the environment limited and controlled
Prevent material from entering surface waters and soil. Normally neutralisation is required before waste water is introduced into
purification plants. Do not introduce large amounts into purification plants.

Further information for system design and engineering measures
Observe regulations for protection against explosion.

Stability and reactivity

If stored and handled in accordance with standard industrial practices no hazardous reactions are known.
Relevant information can possibly be found in other parts of this section.

Disposal considerations

Waste treatment methods
Material
Recommendation:
Dispose of according to regulations by incineration in a special waste incinerator. Observe local/state/federal regulations. Ensure
special chem./phys. treatment after discussion with the supplier.

Uncleaned packaging
Recommendation:
Completely discharge containers (no tear drops, no powder rest, scraped carefully). Containers may be recycled or re-used.
Observe local/state/federal regulations. Uncleaned packaging should be treated with the same precautions as the material.

Waste Disposal Legislation Ref.No.(EC)
It is not possible to determine a waste code for this product in accordance with the European Waste Catalogue (EWC) since it is
only possible to classify it according to how it is used by the customer. The waste code is to be determined within the EU in liaison
with the waste-disposal operator.
